Question

The equation used to predict the total body weight (in pounds) of a female athlete at a certain school is y123+3.39x1.53x2, where x, is the female athlete's height (in inches) and x2 is the female athlete's percent body fat, measured as x2%. Use the multiple regression equation to predict the total body weight for a female athlete who is 67 inches tall and has 27% body fat. The predicted total body weight for a female athlete who is 67 inches tall and has 27% body fat is pounds Round to the nearest tenth as eeded

Explanation / Answer

y = -123 + 3.39x1 + 1.53x2

Given that, x1 = 67 inches

x2 = 27%

So, the predicted body weight of the female athlete = -123 + 3.39x67 +1.53x27

= 145.4 pounds
